This is the 5th post in the Hibernate hard facts focus series. In this article, I will show you how to manage logical DELETE in Hibernate

This is the 6th post in the Hibernate hard facts focus series. In this article, I will show you how to use the fetch profile feature introduced in Hibernate 3.5. Lazy loading is a core feature in Hibernate: it saves memory space.

Hibernate fills the lazy loaded attribute with a proxy that makes the SQL request when the getter is called.

This is the 7th post in the Hibernate hard facts focus series. In this post, we’ll have a look at the difference between saveOrUpdate() and merge().
